# Data residency

> Where message content is stored

See [Data & security](/guides/data-and-security) for what this means for
building your integration. This page is the policy statement.

<Info>
  Stored in AWS eu-west-2 (London). No automatic expiry: messages are kept
  until deleted. Deleting a message removes it from all clients and APIs
  immediately. Notifications already delivered to devices are not recalled.
</Info>

This applies to message content sent through the public API: `text`,
`blocks`, and `metadata`.
